I've spend 3 Months business related in Dhaka. I had a wonderfull stay in that amazing city. Rafiqul, the host, is a super friendly and relaxed guy living in germany. The person you will have contact most and which is your contact person in Bangladesh is his brother Jahagir. I had a really warm welcome and Jahagir did his best to make my stay as comfortable as possible. If you need something, just tell him and he will arrange everything. As example i had problems with the water-supply for two days. When I mentioned it to Jahagir, he installed a completly new waterpump the next day.
The room has a new Wifi-router which works perfectly, a computer you can use, a TV, Fridge, Kitchen, different Fans for the hot season, Western-style bathroom (no hot water though) and the doors all lock thight (a previous poster mentioned that they don't). Dhanmondi is a neighborhood right in the middle of Dhaka and everything you need to buy you can get within a few minutes. Bashundara City Mall is a 10 Minutes Walk and you can get everything there). It is away from Gulshan and Banani, the fancy expats-neighborhood, so you will be the only tourist around (which I like when i travel). But don't worry, you are absolut safe there and the people you will met on a daily base are really nice and will threath you as a friend within minutes (and will remembre you). You have a lot of privacy on your rooftop and it's as calm as that city can be. To find your way to the apartment it's the easiest to say to the Rikshaw/GNC driver to drop you in front Green Life Hospital. Then you just turn into Crescent Road and it's the first Building/Door on the right.
The room is well maintained, but it still is an old building in Dhaka so keep that in mind when you have your expectations about it. Yes you will have mosquitos and geckos sometimes. If you can't handle that you better look for a fancy Hotel in Gulshan 2. If you want to have your own home away from home in a normal Dhaka neigborhood and really have contact with the people of that city I can recommend that apartement honestly. Especially when you stay a little longer but want to have your own furnished room you get a pretty good price/value here. Not to mention the help you get from Jahagir if you need it.
I will stay here again when I'm in Bangladesh again.
